5.5. Channels and Packages
5.5.1. System List
Refer to Section 5.4.1 for details.
5.5.2. Channel List
A channel is a list of Red Hat Linux packages. Channels are used to choose packages to be
installed on a system.
There are two types of channels:
base channels and child channels . A base channel consists of a
list of packages based on a specific architecture and Red Hat Linux release. For example, all
the packages in Red Hat Linux 7.1 for the x86 architecture is a base channel. The list of pack-
ages in Red Hat Linux 7.1 for the Itanium architecture is a different base channel. A child
channel is a channel associated with a base channel but contains extra packages. For exam-
ple, an organization can create a child channel that is associated with the Red Hat Linux 7.1
for the x86 architecture and that contains extra packages needed only for the organization,
such as a custom engineering application.
A system must be subscribed to one base channel and can only be subscribed to one base
channel. A system can be subscribed to multiple child channels of its base channel. Only
packages included in a system’s subscribed channels can be installed or updated on that
system.
The
Channel List page provides a list of all base channels and their child channels. Click-
ing on the name of the channel (base or child) displays the Channel Details page. Refer to
Section 5.5.3 for details.
5.5.3. Channel Details
If you click on the name of a channel, the
Channel Details
page will appear. This page
contains the following tabs:
•
Details — General information about the channel and the parent channel if it is a child
channel.
•
Package List — List of packages in the channel.
Clicking on a package name displays a set of tabbed pages with information about the
package. This information includes which architectures it runs on, the package size, build
date, package dependencies, the change log, list of files in the package, and which systems
have the package installed. Refer to Section 5.5.5 for more information.
If you are looking for a specific package or a subset of packages, you can use the package
filter on the top of the list. Entering a substring to search for will search all the packages
